XVALTER L. l-IARDING, OF LIVINGSTON, TEXAS.

WICK-REGULATOR FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 529,382, dated November20, 1894.

Application led April 17, 1894. Serial No. 507.913. (No model-l To allwhom t may concern:

Be it known that I, WALTER L. HARDING, a citizen of the United States,residing at Livingston, in the county of Polk and State of Texas, haveinvented a new and useful Vick- Regulator for Lamps, of which thefollowing is a specification.

My invention relates to an improvement in those-lamp-wick regulatorswhich consists of a threaded rod operated bya nut and connected to thewick, whereby the wick may be raised or lowered by operating the nut;and the invention lies in an improved connection between the wick androd, by which the wick can be raised with more uniformity and ease.

ln the accompanying drawings: Figure 1 represents a section of a lamphaving my improvements applied; Fig. 2, an enlarged perspective view ofthe rod and its attached rim; Fig. 3, a similar view of the tube orsleeve for embracing the wick; Fig. 4, a horizontal section, showing inparticular the mode of connecting the rim of the rod to the sectionalsleeve; Fig. 5, an end elevation of the sleeveembracing rim.

The reference numeral 1 indicates the lampbody, which is shown asprovided with the central draft-tube 2,and tubular wick 3, all of whichmay be of any preferred construction.

Located on the tube 2, and capable of a vertical reciprocating movementthereon, is the sleeve or short section of tubing 4, which snuglyembraces the tube 2, but so as to be capable of the movement aforesaid.This sleeve is adapted to have the wick 3 passed over it, and to be heldin engagelnent therewith by the sectional sleeve 5, which is adapted toembrace the wick and sleeve 4, and to clamp the wick and itself in rigidengagement therewith.

The sleeve 5 is formed of two vertical sections hinged at one of theiredges, and adapted to swing horizontally on said hinge, and provided atthe remaining edges with the clasp or other securing device 6, wherebythe sleeve, after having been placed around the wick, may be clampedthereagainst, as before stated. Formed on the lower edge of each sectionof sleeve 5 are the peripheral anges 7, which are provided with thebeveled contiguous ends 8. These ends S serve the double purpose ofpermitting the sections of sleeve 5 to swing on their hinge, and toallow the clamp or securing-arms of the operating rod to be attached tothe sleeve 5, as will be more fully described hereinafter.

9 indicates the rod foroperating the invention, and this is formed of anintegral piece of metal, bent to comprise two parallel sections 1O and11. The section 11 is about twothirds the length of the companionsection, and is provided with the semi-circular arm or rim 12, which isformed integral with, or rigidly secured to, its lower end, and whichcurves to form a true semi-circle outwardly from the section 11, and oneach side thereof, and is of such a size that it will embrace theflanges 7 of sleeve 5.

Formed integral with the rim 12, and on the lower and inner peripherythereof, is the flange 13, which forms a rabbet-groove 14, iu whichone-half of each of the flanges 7 lies, and the parts are so shaped thatthis connection will be a snug one.

The ends of the rim 12 are each formed with the inwardly-extending studs15 thereon, which lie far enough above the fiange 13 to permit theflanges 7 to lie upon the former flanges and under the studs, wherebythe flanges 7 are connected to the rim 12, in a way which will be secureagainst all movement of which the sleeve 5 is capable, since it cannotmove horizontally, and its vertical movements will be suppressed by thestuds 15 and flange 13, respectively. The anges 7, of the sleeve 5, aresecured in theirseat in the groove 14 and under the studs 15, by meansof the beveled or inclined ends 8, which, being contiguous, formapproximately two V-shaped or triangular openings in a practicallycontinuous flange, and thereby allow the studs 15 to move upwardlythrough the openings, until the studs lie in a plane above the flanges7, and until further independent upward movement is suppressed by theengagement of anges 13 and 7. Vhen the parts assume this position thesleeve 5 is turned axially one-fourth a revolution, so as to put thestuds 15 and ends 8 out 0f vertical alignment, and make accidentaldisplacement of the rim 12 and sleeve 5 quite impossible. From the rim12 the section 11 extends vertically through the oil tank or chamber ofthe lamp and out the opening 16, formed in the upper side thereof.

This opening should be provided with a suitable box, or its equivalent,whereby the oil is prevented from passing out the same, and whereby therod-section 11 is cleaned of the oil which would otherwise cling to itafter passing through the oil in the chamber aforesaid. The rod 9 isthen bent outwardly and downwardly and the latter portion passed throughthe tube 17, which, in turn, passes downwardly and through the oilchamber, and opens, at its lower end, outside of said chamber.

The last-named portion of rod 9, or the part 10, projects below the tube17, and is provided, at its lower end, withthe threads 18, which are ofa quick pitch, and adapted to operate with the nut 19. This device, nut19, is so related to the other parts of the device that it will be freeto revolve and consequently move the rod 9 vertically, and yet beincapable of vertical movement, for this attribute is essential to theeffective operation of the nut. The means for attaining this result maybe any of the various devices known to mechanicians, but Iprefer toprovide the swinging stud 20, which is adapted to swing towa'rd and fromthe nut and engage with the annular groove 21 thereon, whereby the nutis allowed to turn axially and is held from vertical movement.

To regulate a wick having my improvements applied, the nut 19 is turnedto move rod 9 in the requisite direction, which will be followed byasimilar movement of the sleeve 5, and a consequent movement of sleeve etand wick 3, owing to the fact that sleeves 5 and 4 are clamped togetherand with the wick 3 between them. When the wick has been raised orlowered as desired, the movement of nut 19 is stopped and the partsallowed to remain until a second operation becomes necessary.

It will be seen that the movements of the wick will be free andunrestrained, since the sleeveC is loosely mounted on the tube 2andrigidly connected to sleeve 5, thus enabling sleeve 5 to move with it,and allowing all of the movable parts free movement in their respectivelines.

Having described my invention, what I claim is 1. In a lamp, thecombination of a central draft-tube, a sleeve slidably mountedthereonand adapted to have the wick passed over it, a clamp adapted toembrace the wick and sleeve and to secure itself and the wick and sleevein rigid connection, the clamp having latter being located above theplane of the rabbet-groove and adapted to pass through the notches inthe flange, and thereby admit the flange to pass into the rabbet-grooveand to hold said flange in the rabbet-groove by moving the notches andstuds out of vertical alignment, substantially as described.

2. In a lamp, the combination of a central draft-tube, a sleeve slidablymounted thereon and adapted to be secured to the wick, the sleeve havinga notched flange formed thereon, a rod capable of Vertical movement andfor raising and lowering the sleeve, and a semicircular rim secured t0the rod-and having a rabbet-groove thereon adapted to receive the flangeof the sleeve, and a stud on the rim and arranged above the plane of therabbetgroove,thestud being adapted to pass through the notch in theflange on the sleeve so as to permit the flange to enter therabbet-groove, and to hold said flange therein by moving the stud andnotch out of vertical alignment, substantially as described.

3. In a lamp, the combination ot' a central draft-tube, a sleeveslidably mounted thereon, a second sleeve formed in two verticalsections hinged to each other and adapted to embrace the first sleeveand clamp the wick between the two, each section of the second sleevehaving a flange formed thereon and provided with beveled contiguousends, whereby the sections are allowed to swing on their hinge, and twonotches formed in the otherwise continuous ange, avertically-reciprocating rod for operating the sleeve, and a rim securedto the rod, the rim having a rabbet-groove, and two studs formedthereon, the studs being located above the plane ot' the rabbet-groove,and adapted to pass through the notches in the flange on the sectionalsleeve, so as to allow the flange to lie in the rabbet-groove, and to'hold the Iiange in place by moving the notches and studs out of verticalalignment, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afxed mysignature in the presence of two witnesses.
